Fig. 7. Native porcine valve bending mechanics for tricuspid, mitral, aortic and pulmonary valves.

a) Valve thickness (Fig. 1f) and b) bending elastic moduli (Fig. 6). c) Consistent with the biaxial response illustrated in Fig. 5 atrioventricular valves (mitral and tricuspid) showed a higher bending rigidity (EI) when compared to the outflow track (aortic and pulmonary) valves. This result was also in agreement with the valve fiber bundle diameter quantification presented in Fig. 8.
